Abstract: A buffer solution is charged in a reaction container so that enzyme electrodes can be immersed in the buffer solution. Current values between the enzyme electrodes, to which a voltage is applied, are sampled at predetermined-time intervals. A decreasing curve of current is predicted on the basis of the sampled current values. A sample is injected in said buffer solution at an early time before the current between enzyme electrodes become stable, whereby oxidation reaction of a specified component of the sample is caused. A current value I.sub.1 between enzyme electrodes is measured and simultaneously a current value T.sub.2 on the decreasing curve is obtained at a point that a predetermined time passes from the sample injection point to obtain a current increase from the sample injection on the basis of a difference of the current values I.sub.1 and I.sub.2. A quantity of the specified component of the sample is obtained on the basis of the current increase.

Abstract: An image forming device supplies developing agent to developing portion for developing a latent image in devices such as those using electrophotography. A developing agent supplying body is formed of soft synthetic foam resin material imparted with conductivity, and imparted with physical properties such that a property of F, defined by F=S.multidot..rho./H, is between 72 and 114, where H is hardness, .rho. is density, and S is cell count of bubbles. Alternatively, the developing agent supplying body may be configured such that a moving speed of a developing agent supplying body at a contact surface is 1.4 to 1.7 times that of a developing agent transporting body. Both the above configurations ensure that an optimal amount of developing agent is supplied to the developing agent transporting body for transporting developing agent to the developing portion, thus allowing for good quality printing to be obtained.

Abstract: A monocrystal of a R-T intermetallic compound containing R (at least one lanthanide element inclusive of Y) and T (at least one transition metal element such as Fe, Co, Ni, Cr and Mn) is grown by a solid phase method. First a precursor in which a primary phase of the intermetallic compound and a low-melting eutectic crystal phase exist is prepared. The precursor is successively heated from one end to another end while it is often contacted at one end with a seed crystal. Then the low-melting eutectic crystal phase functions as a flux intergranular substance to ensure the consistent manufacture of a monocrystal aligned with the crystallographic orientation of the seed crystal or at the start-of-heating point.

Abstract: There is provided a method for the determination of a glucose concentration in a whole blood utilizing a biosensor. A correction of the measured glucose concentration for dilution error introduced by the solid component of blood cells is calculated based on the change in glucose concentration measured before and after significant glucose has diffused from blood cells into the buffer used to dilute the sample. Thus, the need to centrifuge blood samples to obtain a cell-free serum sample for glucose determination is eliminated.

Abstract: A one-component developing apparatus includes a developing roller which holds a one-component developer and feeds the developer to a photosensitive drum, and a developer layer thickness regulating blade. The regulating blade has an edge which is parallel with a surface of the developing roller and the edge regulates the thickness of the developer layer on the drum. The edge is constructed by being machined along a direction in parallel with the surface of the developer roller. The edge of the regulating blade may be either sharp or rounded.

Abstract: A viscous liquid applicator which comprises a cylindrical container containing a viscous liquid therein, and an applying member fitted in the distal end portion of the container in such a manner that it is capable of reciprocally moving in the axial direction of the container. A space is formed between the inner surface of the distal portion of the container and the outer surface of the applying member. The viscous liquid can be taken out of the container by pressing it to pass through the space, thus adhering the applying material on the outer surface of the applying member as the applying member is moved into the container. The applying member may be provided on its outer surface with a groove or grooves through which the applying material can be taken out of the container.

A voltage is supplied to the roller to electrostatically move the toner particles from the roller to the latent image, and a voltage is applied to the blade member to inject an electrical charge to the developer layer. When an operation of the device is started, a supply of the voltages to the roller and blade member is carried out after the roller is rotated.

Abstract: A liquid applicator includes a case for containing a liquid and an applying member, housed in the case, for applying the liquid. The case is broken to expose the applying member, thereby allowing application of the liquid via the applying member. The shape of the distal end face of the applying member is formed to be substantially rhombic or elliptic so that the thickness in one direction is larger than the thickness in another direction perpendicular to the one direction. By moving the distal end face of the applying member in the another direction perpendicular to the one direction, the liquid can be applied on a wide affected part within a short time period.
